The Mariners are looking better for next year with strong, young, new guys settling into their roles, but it would definitely help to add in some quality veterans to create a balance. There are certainly some spots that could use an upgrade, and there are some good looking free agents on the market this year as well as some big players on the trade block.
GM Jack Zduriencik and the Mariners have money to spend since the young guys filling a lot of starting spots come cheap. However, they don't have as many trade assets for the same reason.
Whether it's through a trade or a pick-up, it's likely that Jack Z will take some level of action this offseason to beef up the starting lineup.
